From that angle, we can also argue that losing a door or a plane or two during flights is not a big issue for Boeing and people in general, because it's the only problem known with these planes, and it happens pretty rarely, no?

Heck, even if we believe Boeing, it's the pilots' problem who are not retrained for the new plane which doesn't need training.

Honestly, also this Boeing thing smells like an overblown hysteria campaign to pump American planes.
